ABSTRACT:
A driving current control circuit capable of controlling the logarithmic base current of two transistors in a current driver to control a drive current for a motor. This control circuit controls the current of the current regulator depending on a control signal, thereby controlling the driving current for the transistors in the current driver. The control circuit includes an output current mirror composed of two output-side transistors and a single input-side transistor. The two output-side transistors control the inflow and outflow of the driving current for the current driver. A single phase compensating condenser is connected to the input-side transistor. This arrangement makes the entire circuit simple and compact and causes an improved controlling characteristic.
